To all whom t may concern:

Be it known that we, FLOYD G. WITHROW and HAROLD O. VAN ANTWERP,citizens of the United States of America, residing at a Grand Ra ids, inthe county of Kent and State of yi/lichigan, have invented certain newand useful Improvements in Antirattlers; and we do hereby declare thefollowing to be a full, clear, and exact description of the invention,such as will enable others skilled in the art to Which it appertains tomake and use the same.

rlhis invention relates to anti-rattlers and more particularly to suchdevices adapted to eliminate vibration of the so called brake rod in andadjacent which supports it intermediate its ends and in which the saidrod moves longitudinally in performing its functie The deviceembodyinethis invention is herein specifically descri d and illustratedin the accompanying drawings as applied to a certain structure common tothe Ford automobile in which the said brake rod and a member known asthe radius rod extend substantially parallel. The brake rod support isclamped to the radius rod and has an extending arm provided with an eyethrough which the brake rod extends. Since these correlated parts do notalways maintain perfect alineinent the said eye must be sufficientlylarge to ermit free movement of the brake rod therein under allconditions and as there is no tension on the brake rod when the brakesare released to drive the automobile the said rod is ordinarily free torattle and vibrate in the said eye causing a very annoying sound.

'llhe object -of this invention is to provide 40 a. simple, cheap andeffective device which will eliminate the vibration ofthe brake rod inthe eye of the support but which will not interfere with thelongitudinal movement ofthe rod necessary to its proper functioning.

These and other useful objects are attained by means of the devicehereafter fully described and particularly claimed, reference hein hadto the accompanying drawings 5@ in w ich,

Like numbers re er to .like parts in all` of the figures.

'1 represents the brake rod and 2 the radius rod which extendsubstantially parallel, the brake rod servin as an actuatin mediumbetween the bra e of a rear whee and a hand lever at the drivers seat.As the brake rod is of considerable length it is su ported intermediateits ends by the bra e rod support 3 which is clamped to the radius rodand has a laterally extending arm 4 terminating in an e e 5` throughwhich the brake rod extends. he brake rod in performing its functionmoves longitudinally in the eye 5 and this eye either by intent or wearor strain is usually loose about the rod. When lthe brake is released sothat the automobile ma be driven, ythe tension is released from the rakerod and its middle portion hangs loosely in the eye of the support.

flhe anti-rattler is formed of a single piece of spring Wire the middleortion of which is bent to form an elongate loop 6. which extends aboveand transversely of the brake rod and radius rod and bears upon theupper surfaces of these members the respective ends of the loop 6 beingcurved downward as at 7 to retain it in place. The two strands of Nowire joining near the center of' the loop extend parallel a shortdistance and are each curled into coiled springs 8 near Ithe center ofthe device and these spring portions lie beneath and engage the underside of the arm 4 of the brake rod support which is channel shaped withits flanges dependingr on either side of the spring portions 8 andprevent the anti-rattler from endwise move-l ment. The wire strandsafter forming the springs 8 extend substantially parallel in the form oflingers 9 each of' which terminates in an outwardly extending hook 10,one of which engages the upper surface oi the radius rod 2 and t-heother hooks over the brake rod 1.

The springs 8 are originally coiled to cause the fingers 9 to extend ata downward angle and when in operative position the loop 6 at one end ofthe device serves as a cross head to anchor upon the brake rod andradius rod, tlc spring portions 8 act as a fulcrum bearing on the underside of the arm L.tand the fingers 9 through the hoolts ll) exert aconstant downward pressure on-the radius rod and brake rod, thispressure being suliicient to hold the brake rod snugly against the lowersurface of the eye 5 and effectually revent all rattling between thesetwo mem ers.

rlhe tension and friction thus exerted is not sufficient to impede thelongitudinal movement of the brake rod when manually operated but willtend to retain the said rod in place against inadvertent movement fromjarring of the machine while in motion.

'lhe res ective sprin members 8 are preferably coi ed closely a jacenteach other so that they will by engagement, one with the other, be selfsupporting and counteract any tendency to turn over vby en agement withthe varm l which is incline at this point.

rlhe modified structure which is illustrated in Figs. 4: and 5 islikewise made of a single piece of spring wire,its middle portion beingformed in a hook 11 which extends under the arm 4 and adjacent the mainbody of the support 3. The wire strands thence extend "over the radiusrod 2 and downward at its rear side and are bent under its lower edgeand each formed into coils 12 which lie adjacent the front surface ofthe radius rod. 'lhe strands thence incline upward in the form oflingers 13 each of which terminates in a hook 14 which engage the brakerod 1 at opposite sides of the eye 5 and press it outward into closeengagement with the outer surface of the eye.

The modification shown in Figs. 6 and 7, also being made of a singlepiece of spring "wire, has its middle portion formed into a loo 15 whichextends under the arm 4 an the strands extend over, back of and underthe radius rod as in the modification of Figs. 4 and 5. The strands arethence coiled into extension springs 16 which incline diagonally upwardtoward the brake rod and each terminates in hook 17 which embraces thebrake rod and pulls it inward and down into close engagement with theside of the eye 5.

The preferred embodiment of the invention, and also the modificationdisclosed herein are simple and chea in construction and easy to apply,they e 'ectively prevent vibration of the brake rod at the point ofsupport-and eliminate rattling between'the rod and supporting member.

While the anti-rattler has been shown and described as applied to aspecilic structure it is to be understood that this inventioncontemplates the use of similar devices applied to analogous structureswherein a rod is supported in the eye of an arm in a similar manner.

We claim:
